United States Patent RAIL ANCHOR ATTACHMENT FOR RAIL TIE PLATE Henry D. Robinson, Sorrento, Calif. Application August 4, 1950, Serial No. 177,665

2 Claims. (Cl. 238332) This invention appertains to improvements in railanchoring means, and has for its primary object to provide a rail anchor attachment for a conventional tie plate for preventing creeping of a rail and adapted to be secured to the tie plate and rail without modifying the construction and function of the tie plate.

Another object of this invention is to provide a rail anchor which is adapted to be installed as an attachment to a standard tie plate, and which, in use, will not interfere with the installation or repairing of standard rail supporting structure.

These and ancillary objects and structural features of merit are attained by this invention, the preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in perspective of a supporting structure for a rail, with a rail anchor embodying the features of this invention operatively associated therewith;

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1; and

Figure 3 is a top plan view of the rail anchor.

Referring more particularly to the accompanying drawing, a conventional rail is illustrated in an operatively mounted position on a cross-tie 12. A tie plate 14 is fixedly mounted on the cross-tie and abuts the base flange 16 of the rail, being secured thereto by spikes 18. The foregoing is, of course, standard construction.

The rail-anchor 20 provided by this invention is adapted to be fixed to the tie plate and clamped on the base flanges of the rail in a manner to anchor the rail against longitudinal creeping. The rail anchor 20 includes an elongated rod 22 having on one end an inwardly and upwardly curved clamping hook 24 which is adapted to embrace one of the base flanges of the rail, as illustrated in Figure 1. The rod is disposed transversely beneath the rail, and an anchor plate 26 is carried by the threaded end 28 of the rod.

The anchor plate 26 is preferably rectangular and includes a plane plate portion 30 which is welded at one end to the adjoining end 32 of the tie plate, as at 34. A transverse groove or recess 36 is formed on the under side of the plate portion 30 for the reception of an elongated sleeve 38, within which the rod 22 is disposed. The sleeve 38 is securely fixed in the recess 36, though, of course, the sleeve could be formed integrally with the plate, or a transverse bore could be provided in the plate to constitute a sleeve for the reception of the rod. Nuts 40 are threadedly engaged on the threaded end 28 of the rod to lock the anchor plate 26 and the clamping hopk 24 securely on the opposing base flanges of the rar The plate 26 is formed with means for securely engaging the outer edge of the base flange 16, and for this purpose, a shoulder or enlargement 42 is formed on the upper face of the plate and terminates in a vertical shoulder 44 spaced inwardly from the edge of the plate and defining a horizontal seat or shoulder 46. The outer edge of the base flange 16 is engaged on the seat 46 and abuts against the vertical shoulder 44. In this manner, the plate 26 is clamped on the edge of the base flange 16, with the clamping hook 24 engaging the opposing base flange.

In installing the rail anchor on the rail, the plate 26 is welded, as described, to the tie plate, and the rod 22 is inserted through the sleeve 38, with the hook 24 hooked on the opposing base flange. The nuts 40 are then threaded on the end 28 of the device to tighten the rod on the rail.

In use, any tendency of the rail 10 to creep longitudinally will be resisted by the engagement of the bolt 22 and the anchor plate 26 with the rail, supplemented by the engagement of the tie plate and the heads of the tie plate spikes 18 with the rail flanges.

If desired, the plate 30 may be formed as an integral, lateral extension of the tie plate 14, the only requisite being that the plate be aflixed to the tie plate in such a manner that the rod 22 will be positioned on the outside of the rail.

What is claimed is:

1. The combination with a tie, a rail arranged transversely of said tie and having opposed base flanges resting upon said tie, a tie plate beneath said rail and resting upon and fixedly secured to said tie and having a portion engaging the adjacent flange of said rail, of an anchor operatively connected to said tie plate and to the flanges of said rail for holding said rail against longitudinal creeping movement, said anchor comprising an anchor plate having a side edge abutting and fixedly attached to a side edge of said tie plate and having an end edge provided with means engaging said one end edge of said adjacent flange, a rod positioned transversely of and below said rail and extending slidably through said anchor plate and having one end provided with a hook embracingly engaging the other flange of said rail, and securing means on the other end of said rod for attaching said anchor plate to said rod.

2. The combination with a tie, a rail arranged transversely of said tie and having opposed base flanges resting upon said tie, a tie plate beneath said rail and resting upon and fixedly secured to said tie and having a portion engaging the adjacent flange of said rail, of an anchor operating connected to said tie plate and to the flanges of said rail for holding said rail against longitudinal creeping movement, said anchor comprising an anchor plate having a side edge abutting and fixedly attached to a side edge of said tie plate and having an end edge provided with means embodying a horizontal seat and an upstanding shoulder engaging said one end edge of said adjacent flange, a rod positioned transversely of and below said rail and extending slidably through said anchor plate and having one end provided with a hook embracingly engaging the other flange of said rail, and detachable securing means on the other end of said rod for attaching said anchor plate to said rod.
